Duke's Big Four by Duke Ellington (what other Duke is there?)on Pablo is also a really great recording. They really got the kick-drum slam on this one.
New Air release...wow...talk about a recording...simply world class my friends...comes out 3/5 in the states...but I already have it!
I picked up Beck "Sea Changes" yesterday based on the recommendations above...and it's fabulous.

A few other which sound great to me:

Knopfler - Shangri-la
Alice in Chains - unplugged
Tool - Undertow
i didn't see these two on the list, but maybe i missed them...

Lucinda Williams- West
Patty Griffin- Children Run Through

put em and kick back!!!
I just picked up Rebecca Pidgeon's greatest hits on Chesky. By far, the best engineered cd I own
